Excel object in Word template

Does anyone have the same problem? For a very long time now we have Word templates with an excel object embedded. We use them in our order forms. Since a few weeks my object does no longer react the way it did. I enclose one of our templates (converted to a word for this purpose) as an example.

Problem (very difficult to explain but I give it a try):

The object opens in an excel workbook but it reacts differently compared to before.

It used to open "acting as an excel workbook" but still in Word. Clicking outside the object closed the Excel worksheet.

Now, it seems to open as a genuine worksheet/workbook and it does no longer stay active in Word. I have to close the Excell with the x to return to my Word documenten.

When I add lines in the excel worksheet and then I return to my object in Word, the object size cannot be adapted to show all the lines, which I could do before (you had to know how, but it was possible)

I used to be able to modify the size of the object by clicking on the edge markers (before closing the excell object). Now this last action is no longer possible.

I hope this makes sense to somebody.
